I'm in the process of designing sheet metal toolboxes. One is fitted to the right hand side of a vehicle and the other is fitted to the left hand side. I have completed the RHS model and associated pressing and fabrication drawings. I have done a pack and go of all the files. When I mirror the model it creates a NEW model which then needs its own set of fabrication drawings. Is there a way to mirror / invert the original model so the existing drawings automatically update?
